Hawzah News Agency – The merciful prophet of Islam, peace be upon him and his household says:

مَن ظَلَمَ أجِيراً أجرَهُ أحبَطَ اللَّهُ عَملَهُ وحَرّمَ علَيهِ رِيحَ الجَنّةِ، وإنّ رِيحَها لَتُوجَدُ مِن مَسيرَةِ خَمسِمائةِ عامٍ .

'A man who wrongs a worker in his wage, will have Allah annul his worship and prevent him from smelling the breeze of Paradise, which can be smelled from a distance of five hundred years.'
